# 知乎 vs 易学魔方

The clearest difference is in-app purchases: 易学魔方 at none against 知乎's 17. 易学魔方 also leads on ads (none vs shown). 知乎's advantage is update cadence (weekly vs every 7 months) and chart position (#131 vs unranked). On price, device support and iOS requirement there is nothing between them.

Both are free to download. 知乎 sells 13 in-app purchases, starting at $2.99 per month. 易学魔方 asks for nothing beyond the download.

知乎 ships an update weekly, 易学魔方 every 7 months. The most recent releases landed on September 27, 2026 and September 14, 2026 respectively.
